17039 search_fields and multiword searches shelldweller nobody "Django admin automatically splits query string for search_fields and creates a chained series of filters. For example if ModelAdmin instance contains
{{{
search_fields = ('my_field',)
}}}
and the user searches for ""cool search"", the resulting queryset will look like this:
{{{
qs.filter(my_field__icontains=""cool"").filter(my_field__icontains=""search"")
}}}
translating into SQL
{{{
... WHERE my_field LIKE '%cool%' AND my_field LIKE '%search%'
}}}
So far so good. Now if we have anchored or exact search instead:
{{{
search_fields = ('^my_field',)
}}}
Django admin will do exactly the same thing as above and will result in a query like this:
{{{
... WHERE my_field LIKE 'cool%' AND my_field LIKE 'search%'
}}}
which is not ever going to find anything because the same field cannot possibly start with two different strings.
For this reason I am proposing to inspect lookup first and don't split query string if exact or anchored lookup is requested. So we would have instead:
{{{
... WHERE my_field LIKE 'cool search%'
}}}
The code that need to change is between these two lines:
